, we introduce ourselves as leader in manufacturing and supplying of customized pickling tank out of PP, HDPE, by hot gas extrusion welding technology. HOT gas extrusion welding technology is currently used in AMERICA and Europe for purpose of fabrication and welding for improved performance in welding efficiency and enhanced corrosion resistance and life of welding joints.
Welding results have shown zero failure and found reliable joining system extrusion welding is used for thick wall plastic where it is necessary to lay down large volume and homogenous seams. Such fabricated and welding chemical tanks not corroded by aggressive they not affected by exposure to aggressive environment.
The one pass of extrusion welding is enough. Thicker metrical require multiple passes and it increases the cost labor and risk of failure and several heating and cooling cycle harm the properties of thermoplastics. Therefore it is recommended to use hot gas extrusion welding process.
